GMC Sierra 1500 Speedometer Calibrator - Rough Country - '19-'21 free shipping

Introducing the GMC Sierra 1500 Speedometer Calibrator - Rough Country - '19-'21, a must-have for those who have enhanced their vehicle with larger tires. This handy device ensures your speedometer delivers accurate readings, aligning perfectly with your tire upgrades.

Rough Country's Speedometer Calibrator is engineered for simplicity and precision. When you install larger tires, it can affect the accuracy of your vehicle's speedometer. The Speedometer Calibrator addresses this issue by reprogramming your vehicle's computer to match the specifications of your new tires. This plug-and-play device connects seamlessly to your vehicle’s Diagnostic Link Connector Port, providing a quick and efficient calibration process. In just a few moments, your speedometer is recalibrated to reflect your true speed. Additionally, the calibrator not only adjusts the speedometer but also updates the vehicle’s ECM to ensure optimal shift points and recalibrates the electronic stability control system to operate seamlessly with your new tire size.

Features

  • Adjusts speedometer for accurate readings with larger tires.
  • Simple plug-and-play installation.
  • Updates OE ECM to correct shift points for larger tires.
  • Reconfigures Electronic Stability Control.
  • Easily revert to stock settings if needed.
  • Comes with a 1-year warranty.

The Rough Country Speedometer Calibrator is specifically designed for use with gas and diesel 1500, as well as 2500/3500 models (except for the 2022 refresh models). Please note, it is not compatible with any performance programmer and can only be used with one vehicle at a time unless returned to stock settings. Emissions certification is not available for California, so we recommend checking local regulations before purchasing.

If you have any questions or need further assistance, don't hesitate to contact us at our Austin, Texas store at 512-982-9393 or our Los Angeles, California area store at 562-981-6800. We also offer professional installation and customization services at both locations, ensuring your Rough Country Speedometer Calibrator meets your expectations perfectly.

About Manufacturer

Rough Country was founded in 1975 as one of the original off-road shock manufacturers with the classic, yellow-colored shock bodies still seen on the occasional Jeep CJ or squarebody truck to this day! In 1986 Rough Country was purchased by Heckethorn Products Inc, one of the first major manufacturers of aftermarket Jeep Steering Stabilizers.


Soon after, the product line expanded from shocks and steering stabilizers to leveling kits and lift kits for every major make and model. This expansion of the Rough Country brand was guided by a clear vision to provide well-engineered, quality off-road products at an affordable price that any driver could enjoy.  


At present, Rough Country boasts a HUGE lineup of products for tons of makes and models. We’ve expanded into popular categories like LED Lights, Fender Flares, Mesh Grilles, and countless other accessories. Additionally, our product lineup now includes a wide range of shocks and struts, including our new N3 Nitrogen charged, large-bore shocks and Performance 2.0 Struts. In 2018 Rough Country debuted Vertex: a new line of upscale reservoir shocks and coilover struts to rival other high-end options on the market. 


Rough Country strives to offer the highest-quality equipment and a price that won’t break the bank. We’re all truck and Jeep enthusiasts ourselves, and we build on that excitement each day with new ideas, new concepts, and exciting new products.
